In competition with each other and operating under the philosophy that bigger is better, restaurants often serve up a portion size that is equal to two to four normal servings, while menu boards at fast-food restaurants scream “supersized burgers and fries!” Consider these portion-size facts:

In the 1950s, a regular fast-food burger was 2.8 ounces and 202 calories. In 2004, that same burger was 4.3 ounces and 310 calories.

A regular Coke grew from six ounces in 1916 to 21 ounces in 1996.

These days, you can buy a “double gulp” drink that’s 64 ounces and more than 600 calories, and a burrito that’s 1,100 calories or almost three-fourths of the entire daily 1,600-calorie allotment for an average-sized, non-exercising woman. Have them both, and you’re over the allotment.
